SINGLE FLAP VS. DOUBLE FLAP

Single Flap: Dragon single flap options are ideal for temperate climates. It is also a good option for very timid pets who may shy away from a double flap.

Double Flap: Dragon single flap options are ideal for moderate climates. The space between the two flaps creates an insulating air buffer for improved energy efficiency.

Can’t decide between a single or double flap? Every Dragon pet door model can be easily converted from single to double flap with a few easy steps. You can start out with a single flap and upgrade to a double flap at any time by installing an Additional Dragon Flap

ALUMINUM VS. VINYL PANELS

How to Determine if Your Window Frame is Vinyl or Aluminum:

  • Tap the frame: An aluminum sliding window will sound metallic while a vinyl one will make a dull, plastic noise.
  • Measure Track Width: Vinyl tracks are often slightly wider than aluminum. Aluminum tracks are generally 1” wide while vinyl tracks are about 1.5” wide.

Aluminum Panels: Aluminum Dragon panels fit aluminum windows with tracks at least 1” thick. They will fit vinyl windows with tracks at least 1” thick too. However, since vinyl doors generally have wider tracks the panel may wobble a bit.

Vinyl Panels: The Dragon Vinyl Panel is designed to fit in vinyl-framed windows with tracks at least 1” thick. The vinyl pet door panel framing will match your existing window for an aesthetic look. Vinyl is also excellent for cold weather, as it resists the “sweating” (condensation buildup) that aluminum can be prone to in cold climates.

How to Measure Track Width 

You’ll need to measure your window track to choose the correct pet door panel height. Make sure to measure the track thickness, which needs to be at least 1” to accommodate the panel.

Measure Track Width for Sash Windows: For sash windows, measure from the deepest point of one side of the track all the way to the deepest point of the other side of the track to find the track width.

Measure track Width for Side-Sliding Windows: To measure your track height, use a tape measure to find the distance from your bottom track to your upper track.

Locking & Security

All Dragon Pet Door models come with a sturdy thermoplastic Locking Cover to block access to the pet door as needed. The locking cover keeps neighborhood critters out of your home and allows you to lock the flap at night or when you’re away.

Locking Side-Sliding Window Panels: Dragon sideways-sliding window inserts come with a clamp lock that attaches to the flange of the window track at the edge of the sliding window panel. This clamp securely locks the window to prevent access while you’re away. When you want to open your window, simply remove the clamp lock. For additional security, we recommend a wooden dowel or Charley Bar. The Charley Bar can be unlocked in a matter of seconds to open your sliding window.

Locking Sash Window Panels: To permanently lock your Dragon sash, you can install wood screws in the track immediately above the window on both sides. With this method, you would no longer be able to raise the window. For continued use of your window sash, the Charley Bar is the perfect solution. It unlocks in just a few seconds so you can access the sash window.

How to Measure Your Pet

Measuring your pet is crucial to choosing the right door for your pet’s safety and comfort. To find your dog’s shoulder height measure from the floor to the top of their withers. The step-over height should be as low as possible for comfortable use by your pet, especially as they grow older. You can use the formula below:

Step Over + Flap Height = At least 1" Taller than Your Dog’s Shoulder Height.

Insulating Flap Design: Dragon flaps have a two-piece design with a main inner flap and an outer U-shaped piece. This creates a complete seal over the pet door opening to keep the elements out of your home. The flap is lined with magnets that keep it shut against the wind.

Excellent UV Protection: All parts of the Dragon pet door contain a UV-resistant additive to protect the pet door from sun exposure. This minimizes the warping, yellowing, and fading caused by UV rays.

Safe & Secure: Every Dragon pet door comes with a secure locking cover to block the flap when need and keep intruders out.

Flexible Flap Design: The translucent polyolefin elastomer flap is easy for pets of all sizes and temperaments. The flexible flap won’t catch or pinch your pet’s skin as they’re using the door.

Frequently Asked Questions

How can I lock my Dragon Pet Door at night?

Is installing a pet door in a window easy?

Yes, this is one of the easiest pet door styles to install. Dragon window pet doors do not require tools for installation and take just a few minutes to install in your window track.

What if the Dragon sash panel is not wide enough for my window?

You can add a width extension to make your panel fit your window. Start by cutting a board to the height and length you need. Then slide it into the adjustment channel on either side of the door.

Can dogs and cats share a Dragon pet door?

Yes, the flap is light enough that dogs and cats can share the pet door. Just make sure to choose a pet door size that fits all of your pets comfortably.

How tall does my sash window need to be for the sash window panel to work?

The medium flap size has an overall panel height of 21-⅝” and the large flap size panel has an overall height of 25-5/16”. This means that you will need to raise your window to that height to accommodate the sash.
